Application led April 22, 1927. `Serial No., 185,810,

This invention relates to oilingA devices, but more particularly to anair' lineV oiler adapted to bezattached tofa hose or pi used forconveying pressure vfluid rom a source of supply to machines intended tobe actuated thereby, such as rock drills, motors and the like. v

The objects of the invention are to insure a uniform and adequate'supply of lubricant to fluid actuated machines, to prevent frequentinterruptions in the operation of such machines for the purpose ofsupplying haustedfrom the reservoir after each filling thereof.

' Other objects will appear hereinafter,a nd to all of these ends theinvention consists of the combinationJ of elements and arrangement ofparts having the general mode of operation substantially as hereinafter.described and claimed and illustrated in the accompanying drawings, inwhich Figure 1 is a longitudinal sectional elevacoliance with thepractice of the invention, an f Figure 2 is a transverse sectionalelevation taken through Figure 1 on the line 2-2 lookin inthe directionindicated by the arrows. ferring to the drawings, the -inventioncomprises a casing A, the interior which forms a reservoir for oil orlother suitable lubricant which may be introduced into the casingthrough an aperture C normally sealed bya filling plug D. Atone end ofthe casing is formed a projection E having a passageway F therethroughfor the passage of pressure fluid. The outer end of 4o the passageway Fis in this instance thread- `ed forjconnection with a hose or pipe G ofan air line which may lead from asource of pressure fluid supply ,(notshown).

In the opposite side of the casing A 1s formed an enlarged threadedaperture H to receive a correspondingly threaded plug J which, like thecasing A, is also provided e with aprojection K having a passageway Fthreaded at its outer'end to ycooperate with a section L of the hoseline. y

In accordance with the resent invention, the inner ends of theprojections E and terminate in ared walls O and P respectively,-.anhaving at their inner adjacent 55' ends spherical surfaces Q.

1u-- 'bricant thereto and to enable .substantially the entire supply oflubricant to =be ex- -tion of an air line oiler constructed inv ac- Inorder to render the'plug J adjustable so that relative longitudinalmovement between the spherical surfaces Q, may be obtained, liners R maybe disposed between the plug J and the endof the casing A. By imv `thisarrangement, whenever it is desired to move the projection K towards theprojection E one or more liners R may be removed. Qonversely, if it bedesired to move the projectlon K in the opposite direction, an addi- 05tional liner or liners R may be interposed between the casing and thelug J.

Between the spherical sur aces Q and supported thereby is a sphericalmember S having Aa passageway T therethrough to establish communicationbetween the passagewa s Fof the projections. On on'e side /of tli'eImember S is formed a weight U of suitable proportions to preventrotation of the spherical member S with the casing A whenever theposition of the casing is being changed.-`

Anysuitable means may be provided for preventing the member S -fromrocking to such a position that its passageway T may be placed in directcommunication with the reservoir B. In the present instance shoulders Vare formed on the member S for this purpose, said shoulders beingintended to cooperate with the liared ends O and, P. of the projections.35

The member S, in this instance, is rovided with a transverse passage W wichl leads from the passageway T to a longitudinal passage X extendingthrou h the weight near the outermost end thereo to communil90 cate atboth ends with the reservoir B. The .\f wall of the passage X in thisinsta'nce forms a convenient seat for a pin Y disposed in the passage Wto extend through the passage- J way T preferably to a pointnear theupper wall of the member S. y

The pin Y in this instance is of somewhat smaller diameter than thepassage W tov enable an adequate supply of lubricant to .pass betweenthe pin and the wall of the passage W.

' To the end that endwise movement of the pin Y may be limited, a setscrew Z 1s disposed in the upper wall of the member S directly in linewith the pin Y so that when it is desired to hold the pin againstendwise Kv movement and depend only upon transverse movement of the pinto deliver oil into vthe passageways, the screw Z may be turned 1n thedirection of the pin Y to a' point neer; 11

or ugsinst, the uppermost end ol said pin.

ln order to insure an adequate supply ort pressure fluid in thereservoir to not on the surface ot the oil, e tube l; is screwed intothe member S to entend with its free end to e point near the well of thecasing A, that is, to a point above the surface of the oil.

rlhe operation of the device is es bellows: il portion of the pressure tuid such as conipressed air entering the i segeways 'lrcm the oir linewill llow through the tube t; into the reservoir and create a pressuretherein substsntially7 equcl to the pressure in the pascngeways. Afterthe tool or machine to which the lubricant is being supplied is set inoperation, the pressure in the nir line will drop slig itly below thatin the reservoir so that zi, slight unholuncing eldect is Obtainedbetween these points. rllhis unbalanced stets is maintained throughoutthe operetion oit the tool owing to the pulsations caused by; thendmissionand cutoli' ol pressure Jllnid into the tool. '"lhe eilect oilthme pulsations in the reservoir will be to raise the oil in thepossoges :lll and midg owing to the vibratory increment oit the pin Y?the oil will be forced out et' the passage "lll into the pussageway 'llfrom whence it will be conveyed to the tool by the pressure Jduidutilized lier actuating the tool.

lfluring the operation ci the oiler the pin li" muy also reciprocatesomewhut, end sccelerate the delivery oit the oil into the passegeweys.ldfhile such movement ot the pin "il may be edvnntegeous under someconditions, it is` however, not strongly relied upon lor delivering oilinto the psssageweys and under most operating conditions it hes been`found that the best results muy be ob tained by adjusting the screw Eso that the pin will inove only in u transverse direction. This actionoit the pin will have the effect of squeezing the oil out oit thepassage W into the ussagewuy T.

T 1e present invention is particularly adopted for delivering lubricantto rock drills oit' the hand held type or other pneumatic tools usedfor' work in which the drilling periods are ot short duration, thusnecessitotlng 'frequent shifting of the drill and the oiler from oneportion of the worlr to enother. When used under such conditions, und infact under all conditions, the weight ll will et all times maintain thepin il in a vert-ical position and thus hold the outlet opening ci thetube E5 above the suriiece el s the oil.
